#77108 - RACING CLUTCH BELL 18 TOOTH (1M)

Savage/Durable, lightweight, extra cooling

The HPI RacingClutch Bells
for the Savage monster trucks are made from high strength
machined steel and hardened for maximum
durability to provide lasting performance in any driving
conditions.

These Clutch Bells can be used with the stock Savage Spur Gears,
and they are a mandatory upgrade when using HPI Steel Spur
Gears. Machined holes help keep the weight down for
quick acceleration, and the holes also
help cool the clutch shoes for consistent
performance. Each gear is stamped with the number of teeth for
easy identification.

The Racing Clutch Bell is available in different teeth numbers,
giving racers and bashers the choice to adjust the gear ratio to
the terrain for optimum performance.

The more teeth on the clutch bell (or fewer the teeth on the spur
gear) the more top speed with slightly reduced acceleration, ideal
for smooth surfaces or longer straights. The fewer number of teeth
on the clutch bell (or the higher number of teeth on the spur gear)
better the acceleration and torque with slightly less top speed,
ideal for rough terrain, steep hills or short tracks with tight
corners.

The HPI machined RacingClutch
Bells can also be used on the MT-2 and Rush Evo in
combination with the following additional option parts:
